I received a bracelet made with Red Turquoise. Is this a natural stone or manmade? It has somewhat of a small irregular circular pattern in various deep reddish-brown colors, with gold veining. I want to give this to my daughter who is a geologist, and I don't want to offend her. Thank you.

I went on beadonbeads.com, and found the exact bead. It is called a Pyrite Turquoise Composite, coin shaped, PYT-CON-1601.
Can anyone tell me something about this? Thank you again. CLM
